NASA’s New Horizons probe has discovered a new, mountain range on bright, heart-shaped region named Tombaugh Region.

These newly-discovered frozen peaks are estimated to be around 5,000ft high – about 600ft taller than Ben Nevis.

The Norgay Mountains discovered by New Horizons on July 15 are much taller, around 11,000ft, roughly the height of The Pyrenees.

The new range is just west of the region within Pluto’s heart called Sputnik Plain and some 68 miles northwest of Norgay Mountains..

New Horizons has also picked up the first images large images of two of Pluto’s smaller moons.
Nix and Hydra – the second and third moons to be discovered – are approximately the same size, but their similarity ends there.

New Horizons’ first colour image of Nix shows a jelly bean shaped satellite which is 26 miles long and 22 miles wide.

Although the overall surface colour of Nix is neutral grey in the image, the newfound region has a distinct red tint. Hints of a bull’s-eye pattern lead scientists to speculate that the reddish region is a crater.

Meanwhile, the sharpest image yet received from New Horizons of Pluto’s satellite Hydra shows that its irregular shape resembles the state of Michigan.

There appear to be at least two large craters, one of which is mostly in shadow. The upper portion looks darker than the rest of Hydra, suggesting a possible difference in surface composition.

New Nasa camera provides an ‘EPIC’ view of Earth


2AB3935E00000578-0-image-m-3_1437412825315

This is what Earth looks like from a million miles away.

The stunning image, which focuses on America, was taken by the Deep Space Climate Observatory (DSCOVR) and is the satellite’s first view of the entire sunlit side of our planet.

It was presented to the White House today, prompting a tweet from President Barack Obama describing it as: ‘A beautiful reminder that we need to protect the only planet we have.’

The blue marble was captured by the Earth Polychromatic Imaging Camera (Epic) and created by combining three separate images to show the Earth in incredible detail.

The camera takes a series of 10 images using different narrowband filters – from ultraviolet to near infrared.

‘This first DSCOVR image of our planet demonstrates the unique and important benefits of Earth observation from space,’ said Nasa Administrator Charlie Bolden.

DSCOVR orbits the sun at a location called the Lagrange point 1, or L1, It’s from that unique vantage point that the Epic instrument is acquiring science quality images of the entire sunlit face of Earth. Data from Epic will be used to measure ozone and aerosol levels in Earth’s atmosphere, cloud height, vegetation properties and the ultraviolet reflectivity of Earth

SpaceX’s rocket just exploded. Here’s why that’s such a big deal.

An unmanned SpaceX Falcon 9 rocket bound for the International Space Station exploded a couple of minutes after liftoff Sunday morning. It was the third cargo mission to the space station to be lost in recent months.

Elon Musk, SpaceX’s founder tweeted that “there was an overpressure event in the upper stage liquid oxygen tank.” He added: “That’s all we can say with confidence right now. Will have more to say following a thorough” analysis.

NASA officials said it was not clear what caused the explosion. During an afternoon press conference William Gerstenmaier, NASA’s associate administrator for human exploration and operations, said there was “no negligence here.”

The three failures from three different launch providers show “the challenges facing engineering and the challenges facing space flight in general.”

The rocket took off from Cape Canaveral, Fla., at 10:21 a.m., and everything seemed fine until 2 minutes at 19 seconds. Then video of the launch showed harrowing, if now familiar, images of a rocket exploding into a plume of smoke. The Falcon 9 was carrying more than 4,000 pounds of food and supplies to the space station, where American Scott Kelly is spending a year. There were no astronauts onboard.

The explosion also lost many student experiments and a water filtration system. Also onboard was a piece of hardware that would be used to help two new crew vehicles dock to the station.

Artistic Depiction of Pluto 

The National Space Society put together an incredible video preview of the history-making moment. It has the vibe of a movie trailer, complete with epic narration and stunning visuals, and it perfectly captures why space enthusiasts are so psyched about the New Horizons mission.

The video sweeps you through a timeline of the last half century of space exploration using beautiful images of each planet we’ve explored, starting with Venus in 1962 and ending with Neptune in 1989.

New Horizons will reach Pluto and its moons on July 14, and they will be “the farthest worlds ever to be explored by humankind,” the video says.

So far that the sun appears as a faint dot.

Mars has Beautiful Auroras Visible with the Naked Eye, NASA Confirms


AuroraOnMars2 (1)

The stunning light show is similar to the Northern Lights, but a different colour

The Northern Lights are one of Earth’s most spectacular phenomena – with eerie green and red streaks colouring the sky.

It turns out that Mars has a similar light show – visible to the naked eye of anyone on the surface of the Red Planet – but it glows a bright blue.

That’s according to research by planetary scientist Cyril Simon Wedlund from Aalto University.

He and his team carried out an experiment in the lab to simulate the conditions on Mars.

The experiment replicated the Martian atmosphere – made up mostly of carbon dioxide – using a ‘Planeterrella’, a piece of kit that can recreate aurora in the laboratory.

In the case of the Mars experiment, a blue glow formed around the magnetic structures.

They believe that blue is the most prominent color, though red and green may also make an appearance, and that the lights — like ones on Earth — appear several times in a solar cycle, after intense solar activity.

If an astronaut looked to the southern sky from the surface of Mars during one of these flare-ups, the researchers say, he or she would see a sky glowing with blue. Until then, we’ll just have to keep imagining them.

The Auroras are visible in many other planets like Jupiter, Saturn. below are the some photographs of auroras taken by various probes.

See a blue sunset on Mars

The “blue-tinged” sky is caused by fine dust in the atmosphere, according to a statement from Mark Lemmon, a Curiosity team member from Texas A&M University in College Station.

“The colors come from the fact that the very fine dust is the right size so that blue light penetrates the atmosphere slightly more efficiently,” Lemmon said in the statement. “When the blue light scatters off the dust, it stays closer to the direction of the sun than light of other colors does. The rest of the sky is yellow to orange, as yellow and red light scatter all over the sky instead of being absorbed or staying close to the sun.”

Pluto’s five moons captured on camera for first time EVER


ESO-L._Calçada_-_Pluto_(by)

PLUTO’S five moons have been captured on camera for the first time EVER as a NASA probe nears the dwarf planet.

The historic moment was recorded by NASA’s New Horizons probe, which is exploring Pluto and beyond.

Previously the probe has only caught footage of Pluto, which was previously downgraded from its status as a full planet, as well as its largest moon Charon and two of its smallest moons – Hydra and Nix.

However, now, Kerberos and Styx, the dwarf planet’s smallest and faintest moons, are also visible.

Detecting these tiny moons from a distance of more than 55 million miles is amazing, and a credit to the team that built our LORRI long-range camera and John Spencer’s team of moon and ring hunters.

John Spencer, programme scientist of the Southwest Research Institute in Colorado, said: “New Horizons is now on the threshold of discovery. If the spacecraft observes any additional moons as we get closer to Pluto, they will be worlds that no one has seen before.”

NASA said initial viewing appeared to show only four moons visible in the footage, but Charon is also in the images – although it blends into the bright centre of imagery.

Pluto’s four smaller moons were discovered by scientists using the Hubble Space Telescope.

Nix and Hydra were found in 2005, while Kerberos and Styx were discovered more recently in 2011 and 2012 respectively.

The unmanned New Horizons probe will start looking for any more more moons and rings around Pluto this month.

However, astronomers fear previously unseen objects in the dwarf planet’s vicinity may put the spacecraft in jeopardy as it heads toward its closest approach in July – and navigators will be very cautious as it nears.

Alan Stern, New Horizons principal investigator, said: “Detecting these tiny moons from a distance of more than 55 million miles is amazing, and a credit to the team that built our LORRI long-range camera and John Spencer’s team of moon and ring hunters.”

New Horizons was launched towards Pluto in 2006.

Once the probe flies past Pluto and its moons on July 14, the spacecraft will continue flying farther from Earth, investigating other cold bodies past the dwarf planet.

Artist rendering of Messenger above Mercury.

NASA confirmed Thursday afternoon that its Messenger spacecraft collided into Mercury’s surface at more than 8,000 mph, creating a new crater on the planet.

NOTE : MESSENGER (a backronym of MErcury Surface, Space ENvironment, GEochemistry, and Ranging) was a robotic NASA spacecraft which orbited the planet Mercury.MESSENGER became the second mission after Mariner 10’s 1975 flyby to reach Mercury when it made a flyby in January 2008, followed by a second flyby in October 2008, and a third flyby in September 2009, prior to entering Mercury’s orbit in March 2011. It was the first spacecraft to orbit Mercury.

“Going out with a bang as it impacts the surface of Mercury, we are celebrating Messenger as more than a successful mission,” John Grunsfeld, associate administrator for NASA’s Science Mission Directorate said. “The Messenger mission will continue to provide scientists with a bonanza of new results as we begin the next phase of this mission — analyzing the exciting data already in the archives, and unraveling the mysteries of Mercury.”

But before Messenger’s years-long mission came an end, NASA released several new photos of Mercury, as taken by the spacecraft. Some of these photos were composite imagery, combining years of data and photos collected by Messenger, according to CNET.

Here’s one of the incredible false-color images recently published by NASA. The different colors signify variations in mineral composition, topography and other factors on Mercury’s surface.

Newly Discovered Exoplanet Is The Most Distant Ever Detected


o-EXOPLANET-MILKY-WAY-900 (1)

This artist’s conception shows the newly discovered alien planet also Known as OGLE-2014-BLG-0124Lb , which is about 13,000 light-years from Earth.

Astronomers have found an exoplanet nearly 13,000 light-years away, making it one of the most distant planets known to man. This discovery is important not because of the planet itself, a gas giant about half the size of Jupiter, but because what it means for the future of planetary discovery and mapping.

“For context, most of the planets we do know about are a factor of 10-100 times closer than OGLE-2014-BLG-0124,” Dr. Jennifer Yee, a NASA Sagan Fellow at the Harvard-Smithsonian Center for Astrophysics in Cambridge

Far, far away.

The microlensing technique has helped astronomers discover about 30 distant alien planets in our Milky Way’s bulge, the galaxy’s central area of mostly old stars, gas, and dust.

The farthest known exoplanet resides some 25,000 light years away in the bulge of our galaxy, Yee said in the email. The bulge is a very different environment from the Milky Way’s disk, where our own solar system is located.

According to Yee, no exoplanets have been found outside of our galaxy, which spans about 100,000 light years.

Like early explorers mapping the continents of our globe, astronomers are busy charting the spiral structure of our galaxy, the Milky Way. Using infrared images from NASA's Spitzer Space Telescope, scientists have discovered that the Milky Way's elegant s

This artist’s map of the Milky Way shows the location of some of the farthest known exoplanets, including OGLE-2014-BLG-0124Lb.

Comparing planets to planets. Astronomers hope not only to gain a better understanding of the distribution of planets in the Milky Way, but also to gather enough detail about distant planets to compare them with those closer to Earth. More than 1,000 exoplanets closer to home have been discovered by the planet-hunting Kepler mission and ground-based observatories, Space.com reported.

“We would really like to know whether planets form in the central bulge of our galaxy the same way that they do here, near the sun, where the overwhelming majority of planets have been found,” Dr. Andrew Gould, professor of math and physical sciences at Ohio State University, and a co-author of the paper describing the newfound exoplanet, told The Huffington Post.

The Christian Science Monitor reported that the Spitzer telescope is scheduled to observe about 120 more “microlensing” events this summer, which could lead to the discovery of even more distant exoplanets.
